Purposeful Ramblings Through My Mind

This argument has particular force in the case of varicella/chickenpox because the disease is so much more serious in adults and older children than in young children. The vaccine is much more necessary for people who have not caught the disease in early childhood than it is for young children; however, with most kids being vaccinated, non-vaccinated kids aren't necessarily going to catch it in early childhood when it's relatively safe.
